And to you We have revealed the Book, setting forth the truth, confirming the Scriptures which had already been revealed before it and superseding them. Judge, then, between them in accordance with what God has revealed and do not follow their vain desires, forsaking thereby the truth that has come to you. To every one of you We have given a code of law and a way of life. Had God so willed, He could have made you all one community; but [it is His wish] to test you by means of that which He has bestowed on you. Vie, then, with one another in doing good works. To God you shall all return. He will then make you understand all that over which you now differ.
